Specification of Letters Patent.

Application filed December 5,1904. Serial No. 235,564.

the following a specification.

My invention relates to brush machines and more particularly 'to the means for forming the stapleor fastening device which attaches the tuft of bi'istlesto the wood or block; and for conveying such device to the setting jaws and for setting same, also to the means for separating and forming the tuft of bristles, also to the means for adjusting or centering the brush back or block so that the tuft of bristles will attached'in exactly the proper place, and my object is to provide the same with various new and use ful improvements hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings, in. which:

Figure 1 a side elvation of a machine embodying my invention; Fig. 2 is a front elevation of the same with a portion .of the casing broken away showing the cam disk 48; 3 is a section on the line 3'-3 Fig. 1 showing reversesidc of cam disk 48 and other details; Fig. 4 is a detail partly in side view and partly in cross section of the mechanism for separating the bristles into tufts and for conveying the tufts to the setting jaws; is ancnlarged perspective of the bristle fastening device. Owing to the peculiar method in which this fastening de vice operates to retain itself and the tuft of bristles, .i prefer to callit an anchor rather than to use the more general term. staple. we. 6, 7, and S are enlarged detail views rowing portions of anchor cutting and conveying mechanism; Fig. 9 is a cross section of the block centering mechanism; Fig. 10 is an ei'ilarged longitudinal section of the tuft setting and anchor driving device; Fig. 11 is a section of the same on the line 11-11 of Fig. 10; Fig. 12 is a section of the brush back showing one tuft in position and another tuft in the jaws about to be set in the hole;

Fig. is another section of the brush back showing a tuft 1n position and a side view of the anchor. Fig. 14. is a detailed sectional view through the driving pulleys and camdisk operative therewith. Fig. 15 is a detailedfacc view of the cam plate 3:2.

and the l 2 represents the main frame of the machine;'3 the main'driving shaft, which shaft is carried in journal boxes on the frame, such journal boxes being shown at 4 and 5.

8 is a pulley carrying the driving belt and mounted on a sleeve upon the shaft 3. 9 is a taperingv pulley rigidly attached to the shaft 3. 10 and 11 show lever arms so pivoted as to bring about an endwisc movement of this sleeve upon the shaft 3 and thereby carry the pulley 8 to or from the tapered pulley 9. The movement of the pulley 8, by the arm 10, is clearly shown in sectional-detail in Fig. 14. The pulley 8 is r0- tatable and also slidable upon the shaft 3. A sleeve 8 shouldered at one end, is also slidable upon the shaft 3, and is held to the pulley 8 by a collar 8 This sleeve 8 is kept from rotating by its connection with the arm 10. This arrangement of parts constitutes a friction clutch by which motion Patented Jan. 16,1912.

may be imparted to the shaft 3 at the pleasare of the operator.

12 is a cam disk attached to the shaft 3' and having in its face a cam groove 12 of suitable shape, in which travels the roller on the end of the crank arm 13. This crank arm is rigidly attached to the rock shaft 14:,

shape of the cam groove is such as to convey to the said shaft an oscillatory r0- tating motion through only a part, approxi-v mately one-fourth of a revolution. The other end of this shaft 14 carries the eccentrio l5, and thus a reciprocating vertical n10- tion, but through only a short stroke, is

given to the connecting rod 16. These parts 15 and 16 are shown in end View in Fig. 2.

17 is a vertically-sliding block attached to the rod 16 by the screw 18, by which the rod thus imparts vertical motion to the block.

19 and 20 are guides upon the frame, so adjusted as to insure a proper vertical sliding motion .to the block 17. This block -17 canries, prhjecting downward therefrom, t-hestaple or anchor former 22, and. the holder therefor, 21.

I y 23 and 25 are the dies upon the upper surface of which rests the stock from which the anchor is formed, and through which the former 22 passes, punching out and carrying down the anchoror staples. The die 25 is adjustable by means of the screw 31 to insure proper spacing apart of the dies.

. The stock from which the anchor is constructcd is a flat wire shown in Fig. 2 at 108. This passes down between feed rollers 35 and 36. The lower roller '36 is journalcd in a projection 38 of the frame of the machine and the upper roller 35 is carried by a bearing 37 vertically movable on the post- 39. This post 39 has a screw threaded con nection with the projection 38 and iS provided at its upper end by a head 40, and a spring 11 intervenes between such head and a movable bearing 37. It is evident that by screwing down the post 39 that the-pressure on the spring 41 can be increased and there'- by the grip of the rollers upon the wire can be regulated. These feed rollers can be actuated in any suitable manner.

The plate 27, Figs. 6, 7, and 8, is rigidly attached to one-end of a short rock shaft 27. The upper edge of this plate is upon the arc of a circle struck from the center of the said shaft. The lower edges of the dies 23 and 25 are upon the arc of a circle concentric and slightly larger.

A dasher or carrier 26 is rigidly attached to the plate 27. The upper edge of this dasher is u on the arc of the same circle as the edge of the plate 27. The main body of the dasher lies close against the plate, but a part of the dasher near one end and adjacent to the plate is cut away as shown in Fig. 7. The upper surface of the dasher 26 and the plate 27 taken together thus form a smooth curved surface through most of their arc, but have a slightly raised portion near one end as shown in Figs. 6 and 8. This raised portion lies close to the lower edges of the dies 23 and 25 and contains a recess 26 as shown in Fig. 7 suitable for receiving the anchor which has been stamped from the wire 108 by the anchor former 22.

To the dasher 26 and plate 27by-n1eans of a suitable pivot, I attach a link 28, which at its other end is suitably pivoted to the bar 29. This bar 29 at one end is pivoted to any suitable part of the frame and at the other end carries the anchor-supporter 29 This supporter is kept in proper position by the spring 30, Fig. 6, which at one end bears against the said supporter, and at the other end is attached in any suitable place on the bar 29.

When an anchor is formed by the anchor forming mechanism. itis delivered intothe recess 26. The mechanism is so timed that at this point that dasher 26 and plate 27 will be rotated, carrying the anchor beneath the lower edge of the die 23 to the-lower end of such die. The link 28 and the bar 29 are so pivoted and connected that at the same moment the supporter 29 will be lifted and will support the anchor against dropping down any farther as shown in Fig. 8.

I 32 is a finger bar, preferably of thin flat steel, and developed into the carrying fingers 112 and 113. Th1s bar 32 is in turn carried by the slide 12 and longitudinally adjustable thereon by means of the slotted holes and 34. and attaching screws passing therethrough. This slide with the bar 32 carried thereby, is intended to have a reciprocaiing longitudinal motion, and operates in any suitable guides or ways 42 upon the frame. It is actuated and given its reciprocating motion by the actuating mechanism through the connection 124, as hereinafter described.

The finger bar 32 is divided as shown in F 6 and 8 into two lingers, 1.12 and 113, which evidently will be by the spring the material held together, but which will be capable of slight separation as the contin gencies of operation may require. The finger 113, which is the lower one, I have shown longer than the linger 112. At the moment when this finger bar is carried forward to the point where the staple or are chor is held by the supporter 29 the die 23, the dasher 26, and plate 27, this lower projecting finger will pass between the lower projections 114 of the anchor and the middle portion 118 of the anchor will either lie against the end of the arm112, the anchor thereby hanging in a vertical position, or said middle portion 118 of the anchor will pass between the fingers 112 and 113 and be held in a spring grip. The space 26 between the dasher 26 and plate 27 permits the fingers thus to pass therebetwcen. By this means the fingers can take the anchor from the position in which it is thus held and carry it laterally until it is gripped by the setting jaws, as hereinafter described. At a point near its end the main shaft 3 carries the cam 13, the position of which is shown in Fig. 1, and the shape of which is shown in Fig. 3. Upon one side of this cam is located the arm 4:) carrying the roller 14. This arm 45 connected at its upper end by the spring 4-7 to an opposite arm 121, and this spring connection permits the arm 15 to be'actuated by the revolution of the cam 13. The tlillttf) at its other end is pivoted to the frame at 46. This arm 45, through suitable connections 125, 126, and 128 rocks the shaft 27 and thus actuates the anchor-conveying and holding mechanism. The opposite arm 121 carrying the roller 120, also in contact with and operated by cam 43, is pivoted to the main frame at 122, and at its other end is connccted by the rod 124 to the finger carrying slide 42 giving the same the proper reciprocal, longitudinal mot-ion. It is thus evi dent that the cam 13 actuates all of the anchor-eonveying mechanismi Near its extremi ythe shaft 3 carries the cam disk 4'8, shown' in F 2 and 3 and contained in the casing 4:8 which is a part of the framework. Upon the'face s deof this cam disk 18 are cani grooves Wand Fig. 2. in these cam grooves travel respecively the rollers 67 and 68 shown in Fig. 10. is a removable cap for the casing forming the guide or way 63 for the driving mechanism. '5 is a vertically reciprocatin slide operated withinthe casing ii and. actuated by the roller 67 in the groove 67. in another vertically reciprocating slide or frame moving within the slide and actuated through a slot in said slide hy the roller 68 in the groove cs. The lower end of this slide 66 carries the jaws and through the pivotal cm'nieclions and 76.

driver wnich is narrowed and beveled at 71 and which carries at its lower end the im mediate driver or punch 72. This driver head 69 reciprocates w thin the slide 66 and is fastened toythe slide hythc studs 70 and is thus actuated liy the roller 67*. The cam grooves 67 and 68 are of such shape and size that, at the proper time in the o acratiou of the device, the slide 65 and'the attached driver head (59 are carried down a short dis tance from the position shown in F 10. Thereupon the bevel 71 acting as cam, opens the upper end of the jaws and closes the lower end of the jaws causing these lower ends to grip the anchor which has been 1 rsentcd by the carrying fingers and the tunv oil bristles which has been l')l.QSf;lI1lQll by the mechanism designed for that purpose. 'llhercupon, these cam. grooves in their i'urthcr action, cause both slides, represented by 65 and 6G, to he carried downward so that the present the tu'lt and anchor at the to}; of the hole in the hrush block. There-- upon, the slide 65 and the attached driver head ()9 are given further downward motion. 'ihe upper ends oi the aws come in contact with the shoulders 69 and thereby, with said further downward motion, the anchor or staple is driven into-the wood and the tuft is firmly attached. In this operation the lower end of the punch 72 rests upon and drives the anchor, and the cam v,g' 'rcovcs may he adjusted that this punch will come down and rest upon the anchor at any desired point'in the operation. Upon the other side of the cam disk 4% is found the cam groove 50 shown in Fig". In this groove travelstl'ie roller 50, shown in operative position in Fig. This cam groom: cir, or during most of its course, but has two curves toward the center, ine'licatcd by (El and o; The roller is coi'meclcil with thy vcrticail 'lulia'ig lllGCk 49, which moves within a poi non-of the main "frame shown lt is evident, therefore, that at two cz'ent points in the revolution of the cam this sliding hloel; il) will he lifted llv above its normal position. This clock all carries, pivoted thereto, the

li l'tlllli the slide 66 is situated a. v. drive-r head (it) which 1s shouldered at 69 and which carries a downwardly promoting lever arm 51, the point of pivotal attachment being represented by 56.

5'7, 58, and 59 represent means for exerting a downward spring tension upon the upper end of lever arm 51 and outside oi. the point of attachment 56, whereby this lever arm is kept normally in contact with the antifrictional roller 60 carried by the part .2 of the frame to guide the arm 5 'suitabl y attached to the frame. In other words the part 5? is sliclable within the sliding block $9, the lower end of which is forced against the upper end of the lever arm 51 and 0utside of its pivotal connection 56 by means of a spring 58. The upper end of the spring rests againsta retaining plate 59 which 15 attached to the sliding clock 49.

52 is an extension of arm 51 carrying the vertical cylindrical guide 53, and in. this is the centering pin 5% preferably brought to a point in the bottom and rising and falling in the guide 53 under the pressure produced by the spring 55 (see Fig.

128 is guiding surface on the frame and provided with a straight vertical face. l/Vith this tace the arm 51', or a suitable projection thereof, makes contact, and thereby, when in the downward motion of arm 51, this projection. strikes this face or guide, the remaining; motion of arm 51 and of the centering pin 5 will he vertical. Normally the face 128 presents an unbroken surface to the projection of the arm 51, making contact therewith, but a portion of this face represented by 12%, Fig. 3, is made in the form of slide to slide horizontally in the oody of face 128* and provided with means for withdrawing the same a short distance, so that when it withdrawn a notch or recess is produced in this guide face 128. This portion of the guide 12S may be actuated in any suitable manner, preferably by an mm 1.24" engaged by the lever 12.

As the sliding block 49 is carried down after a momentary lifting, the projection on 51 will come in contact with the surface 128, and the centering pin 5% will be carried in :1 directly vertical path down vardly. The parts are so attached to the frame that at this timeathe position of the centering pin, via, the position shown in Fig. 9 will be precisely in the path which will later be taken by the descending setting jaws, and will specify the exact spot which will be reached by the "punch and into which the anchor will he (rawn. The operator handling; the bfrusl i block 11.6 supported on the table 117 will adjust the block so that the bored hole will be, according to his eye, in the proper position. The centering pin will then descend into the hole and correct any in'iperlection in the placing made by the on orator, moving the block to its exactly proper position.

The beveled or pointed n lower end of the centering pm assisting in its lower end it is pivoted to the bar 80 and shown to be in Fig. l. 98 and 99 are two this placihg operation. As the setting jaws begin to descend to drive the anchor to posii tion, the arm 51 will be slightly raised and the sliding stop 1%. will be withdrawn; The spring tension will then throw the projection on the arm 51 into this recess in 128 and the centering pin willtake the position shown in Fig. 1 out of the way of the descending setting jaws. Then, simultaneously with the raising of the setting jaws, the arm 51 will be further lifted and the (entering pin will. take a position considerablyabove and to the left of that shown in Fig. 9, and will then be ready for the-re. verse stroke. The length of time duringwhich the centering device will maintain each position and during which it will be in motion, will be determined by the shape of the cam groove 50 and these timing arrangements will be modified as the operation reuires.

The jaw 74 is provided with a notch 77 adaptedto receive and assist in holding a tuft of bristles in proper position when the jaw 73 is closed thereupon.

The bristle and tuft separating and conveying mechanism is shown in Fig. 1 and parts of it in detail in Fig. 4. Fig. 1 shows the parts in position taking a tuft of bristles just conveyed from the hopper and Fig. l shows the same parts at the point of delivering the tuft of bristles to the setting jaws. The arm 78 pivoted to the main frame at 7t) carries a pin or roller which travels in the cam groove on the hub 6. The arm is thereby given a swing or pendulum motion. At

this bar in turn is supported by the arm 82 which is pivoted to the bar at 81 and the main frame at any desired point. This arm 82 gives direction to the forward end of the bar 80. This forward end carries the bristle jaws 83 and 8 One of these (84) is rigidly attached to the bar, and the other is pivoted at- 108. To the pivoted jaw 83 is connected the rod 101, which rod .is in turn attached to the arm 100, and this arm 100 is attached to the pivot, connecting the arm 78 and bar 80. The attachment of the arm 100 to this pivot is free, and a spring 102 is provided, the pressure of which normally holds the bristle jaws closed as they are trips attached to the ,frame or hopper at proper positions so that in the reciprocating motion of the arm 80 these trips will suc cessively engage with the arm 100, and will momentarily trip the jaws open. The arm 100 passes over the point of trip 99 at the extreme limit of its forward stroke and just at the point where the stroke is reversed, the jaws are held open momentarily. Trip 98 makes contact with the arm 100 at the extrmue limit of the backward stroke, and-the jaws are, therefore held open only momentarily at this point. This operation enables the jaws to open and close upon, and grasp the tuft of bristles presented at the point shown in Fig. -1 and the trip 99 acts upon the arm 100 allowing the jaws to open and release this grasp upon the tuft of bristles and leave the same in the setting jaws at the point shown in Fig. 4. 110 and 111 are the upper and lower walls of the bristle hopper. The series of bristles which lie crosswise of the hopper and are, therefore, indicated in the drawing in cross-section, are shown by 92. The follower 93,.impelled by the cord 94, passes over the pulleys 95, and

the weight 129 constantly presses the bristles toward the tuft-separating mechanism. An

arm 1.03 is pivoted to the main frame, as

shown in Fig. 1, and is operated by a roller traveling in the cam groove in the hub 7 and through thehnk 10 i, rocks the hell crank.

lever 105, which is pivoted to the hopper at 106, and has its horizontal arm 86 carrying a separator head 87. is a comparatively thin piece of metal formed upon anarc of a circle of which the pivot 106 is the center. Near one end of this separator head 87 is anotch 88 of proper size and shape to accommodate a tuft of bristles. The depth of said notch may be varied by means of a thumb screw 89 thus regulating .the size of the tuft of bristles to beseparated from the series 92 in the hop perf This separator head is provided with suitable guide-ways of which is a part.

The rocking of the shaft lOGcauses the arm 86 and the separator head 87 to rise,

the head 87 carrying with it in the notch- 88a portion of bristles of suitable size for a tuft to be inserted in the brush block. This tuft is raised until it is under the movable bristle jaw. 83. carrying the bristle jaws 83 and 8 1 and actuated by the arm 7 8, moves forward a short distance releasing the arm from the trip 98 and allowing-the movable jaw 83 to swing down pressing the tuft of bristles from the slot 88- and gripping such tuft between jaws 83 and 8 1. The separator head is then caused, by rocking of shaft 108, to be lowered out of the way of jaws 83 and 84 after which the bar 80 is caused to have further forward movement and to deliver the tuft of bristles beneath thesetting jaws 73 and 74 which then descend,.as shown in Fig. 4,-and grip them. The bar 80 moving.

anchor'is shown clearly in Figs. 1?; and 18.

This separator head At this moment the bar 80,

izs

the lower projections 114 are driven a short distance into the wood at the bottom of the hole. The upper projections-11.5 are spread so as to enter the wood at the sides of the hole and thus'prevent the anchor from being withdrawn. I

The operation of these parts has. been stated in connection with the description thereof. To summarize the same itis clearly apparent that the bristles are placed inthe hopper and the suitably bored brush block is manually controlled by'the operator upon the table provided therefor. A tuft of bristles is then separated out of the mass in the hopper by the tuft-separating mechanism, and carried by the separator head 87 to the bristle jaws 83 and 84:. It is seized by these jaws and carried to the setting jaws 73 and 74. At the same time the anchor is formed by the anchor-forming mechanism and car- 1 ried by the conveyer and finger bar and delivered to the setting aws. At about thesame time the Centering device, carrying the centering pin, descends and the pin enters the hole in which the tuft of bristles is to be inserted and adjusts that hole and the bloclr in which it 15 bored to the exactly proper position. .The centering device then rises and is removed from the descending path of the setting jaws which. carry the tuft of bristles down into the hole. The anchor which has been carried also by the setting jaws and in a position above the bristle tuft, is then driven down by the punch and the tuft of bristles, indicated by 92 in Fig. 12, doubles up, as shown, around the driver and anchor, and upon the 'withdrawal of the driver, forms the ordinary complete tuft of bristles permanently attached to the brush block.
